Banff is not a very large town. It sits within the much larger Banff National Park. The town limits are set and are not allowed to expand beyond its current limits, lest it creeps into the national park.
We had finished our afternoon of touristy cliches, we were left to our own devices to for the whole evening. The stores along Banff Avenue would be closing up soon. It was a Sunday evening, so we had to work quick if we were to get a little window/real shopping in for the day.
